Aluminum parts and aluminum cavity parts are deformed during CNC machining. In addition to the reasons in the previous section, in actual operation, the method of operation is also very important.
According to the material, structural characteristics and technical requirements of the impeller, the CNC machining plan is analyzed and studied, including the machining process, technical difficulties and technical measures taken. It is recommended to add required process fixture bosses at one end of the impeller, and design and develop a special fixture mold to meet the requirements of impeller processing.
The development of three-dimensional design software provides conditions for low-cost, short-period, and design of positioning fixtures. And it can simulate CNC machining parts for verification. Figure 1 shows a typical metal part with an angle of 45° to the YZ and ZX planes:
The machining of micro parts is also called micro electromechanical system or micro system. It is a micro device or system that can be produced in batches, integrating micro mechanisms, micro sensors, micro actuators, and signal processing and control circuits, even peripheral interfaces, communication circuits and power supplies.
In recent years, civil defense and other fields demand for a variety of CNC machining miniaturization of products continues to increase, the function of the tiny devices, the complexity of the structure, reliability requirements are also increasing. Therefore, it is of great significance to research and develop micro-machining technologies that are economically feasible, capable of processing three-dimensional geometric shapes and diversified materials, and feature sizes ranging from micrometers to millimeters. At present, micro-cutting has become an important technology to overcome the limitations of MEMS technology.
The micro CNC machining technology adopts a fully automatic method to super-finish the surface of metal parts. Through a kind of mechanochemical action, the material of 1-40μm on the surface of the metal parts is removed, and the surface quality of the processed surface reaches or is better than the N1 level of the ISO standard. Micro CNC machining technology is mainly used in the two fields of ultra-precision polishing and ultra-precision brightening.
There are many reasons for the deformation of aluminum alloy parts during CNC machining, and the operation method is also one of the reasons in actual operation. Next, the CNC machining manufacturer of aluminum alloy parts will briefly introduce the operating skills of aluminum alloy parts processing.
Aluminum cnc machining different manufacturers all have their own advantages. Small factories are suitable for rapid prototyping, and large factories are suitable for large quantities. We need to find a suitable CNC processing plant according to our own needs. Generally, the unit price is calculated according to the processing time of aluminum alloy products. So how to calculate the aluminum alloy cnc processing price?
The aluminum shell products use high-quality aluminum alloy profiles, which have the characteristics of solid structure, beautiful appearance, and good heat dissipation performance. It is widely used in industries such as instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, and precision machinery. It is an ideal equipment aluminum housing for high-end instruments and meters. The profiled aluminum shell has the characteristics of light weight, low cost, and mechanical properties (uniform force), and the aluminum alloy is easy to process and has a high degree of heat dissipation.
Provided is an aluminum housing with simple structure, easy installation, effective ventilation and waterproof, and good heat dissipation effect.
